Hutchinson Clincher Tire BLACKBIRD Tube Type 700X28 PV532501 Black/Tan (28-622)

New compound: Mach tread 3.0 and Swift Easy Casing technology Rolling resistance improved by 10% (compared to previous generation tires) Tread width increased by 15%, improving grip and cornering performance New compound: Mach Tread 3.0 and Swift Easy Casing technology adopted Rolling resistance: 10% improvement (compared to previous generation tires) 15% wider tread width improves grip and cornering performance The design is based on the latest wide rims, with a tread that is 15% wider than the previous generation tire. We combined it with the more flexible Swift Easy casing. As a result, the contact area between the tires and the road is wider horizontally than in the longitudinal direction, enabling aggressive cornering and reduced rolling resistance. It comes in two colors, black and tanwall, and three sizes: 26mm, 28mm, and 30mm, and weighs 275g, 290g, and 310g, respectively. The 28mm and 30mm versions are also hookless compatible. The tube type model does not use the Swift Easy casing and has enhanced puncture resistance. It comes in black and tan wall colors and weighs 225g, 245g and 265g.

Please also note that product specifications and weight may change due to the manufacturing process or improvements due to the manufacturer's circumstances. Product description image The key to reducing rolling resistance is a new structure called the Swift Easy Casing. The casing is wrapped around a bead and bonded directly to the central polyamide puncture protection layer. In normal tires, these have an overlapping structure. The final layer of casing wraps the beads on both sides to reduce air leakage. The SwiftEasy casing provides more flexible contact with the road, significantly increasing rolling resistance and comfort, while reducing weight by keeping the 127TPI casing to two layers of overlap. The result is a super fast, comfortable and lightweight Blackbird that weighs just 290 grams with 28mm tires. There's one more technology making its debut in Blackbird. Mach Tread 3.0 is Hutchinson's fastest and most efficient tread compound. This all-new compound has incredibly low rolling resistance and high rebound, resulting in a 25% increase in energy return upon contact with the road. Product description images Paris, March 26th - Hutchinson, a pioneer in French bicycle tire technology, introduces the Blackbird performance road tire. Cycling boils down to this: the three square centimeters of contact between your tires and the road. Since our founding in 1890, Hutchinson has been weaving stories for this small footprint. The exciting next chapter in this story is Blackbird. This is the story of a force that has powered the sport of cycling forward for more than a century, supplying tires to champions and pouring an unquenchable passion into innovation and performance. The Blackbird is the result of four years of research and development and is our fastest tire ever. Rolling resistance has been improved by 10% compared to the previous generation Fusion 5. At the same time, it achieved the longest service life in its class, exceeding 4,000 km in actual driving. Product description image 'Mach Tread 3.0' is 10% harder than the previous 11 Storm compound, has an improved ability to resist the forces that tear the tire apart from road debris, and has a lifespan of over 4,000km. Grip power, which is a performance that contradicts this hardness, maintains the same level as the previous generation.
